This model is equipped with tubeless
tires and tire air valves.
Tires age, even if they have not been
used or have only been
occasionally. Cracking of the tread and
sidewall rubber, sometimes accompan-
ied by carcass deformation, is an
evidence of ageing. Old and aged tires
shall be checked by tire specialists to
ascertain their suitability for further use.
WARNING
The front and rear tires should

WARNING
This motorcycle is fitted
super-high-speed tires. Note the
following points in order to make the
most efficient use of these tires.
Use only the
replacement tires. Other tires
may run the danger of bursting at
super high speeds.
Brand-new tires can have a
relatively poor grip on certain
road surfaces until they have
been "broken in". Therefore, it is
advisable before doing
high-speed riding
conservatively for approximately
100 km (60 mi) after installing a
new tire.
The tires must be warmed up
before a high-speed run.
Always adjust the
pressure according
operating conditions.
